Somaliland. 1903 overprint at foot, 3r. brown and green showing varieties overprint double, one albino and curved overprint, lightly mounted mint. A superb example and a unique stamp. S.G. 23b/e. Photo
Note: Less than 17 sheets of this value were sold, so far no other example of the overprint double have been recorded so it must be presumed that most of the other stamps with this variety were among those which were destroyed as remainders (Image1)

Est. £400-500
